CABINET SG'R-APERQHELDER.

Application filed March 24, 1914.

To all il 10. 7% it may concern:

lie it known that I, THOMAS Witness Co'r'rLn, acitizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Cabinet Scraper-Holder, of which the following is a specification.

The device forming the subject matter of this application is a holder adapted to retain a scraper, and one object of the present invention is to pr vide novel means for clamping the scraper adjustably in place.

Another object of the invention is to provide a device of this type in which the scraper holding head may be detached readily.

Another object of the invention is to provide novel means for limiting the pivotal movement of the head with respect to the handle portion of the device.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construct1on hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

in the accompanying drawing :l*igure 1 shows the invention in side elevation; Fi 2 is a fragmental longitudinal section; Fig. 3 is a perspective of the head; .l g. l is a side elevation showing a portion of the handle; Fig. 5 is a perspective of the scraper; Fig. 6 is a perspective of that portion of the device which is delineated in Fig. 4.

in carrying out the present invention there is provided a handle 1 equipped at its outer end with a transverse cam or arm 2 which is terminally provided with oblong trunnions 8, the cross sectional dimensions of the trunnion being indicated at l and at 5. Projecting from the handle 1 is an ear 6, into which is threaded a screw 7.

The scraper holding head is of archer form and is indicated at 8, the head 8 com-- prising an intermediate portion 9 and arms 10. In the arms 10 are journaling openings 11 which receive the trunnions 3, there be ing reduced slots 12 in the edges of the arms 10, which slots 12 communicate with the openings 11.

The scraper 1 1 may be of any desired Specification of Letters Patent.

form and is bound between the intermediate portion 9 of the head 8 and the fixed cam 2 on the handle 1.

In practical operation, the handle 1 is turned 'until the trunnions 3 lie approximately parallel to the length of the slots 12. Then the trunnions 3 are slid through the slots 12 into the openings 11. Then relative pivotal movement is produced between the handle 1 and the head 8 until the cam 2 binds against the scraper 1 1. VJhen the cam 2 is thus in binding relation with the scraper 1d the cam will compress the scraper against the intermediate portion 9 of the head 8, the trunnions 8 will stand crosswise oi the slots 12, and thus a disengagement ot the handle from the head will be prevented. In order to shift the position of the scraper 14: it is necessary merely to tilt the head 8 on the handle until the cam 2 loosens its hold on the scraper, and then the scraper may be adjusted. The pivotal movement of the head 8 with respect to the handle 1 is limited by the screw 7 which engages the rear face of the scraper 14-. The screw 7' has another function, in that if the scraper 1% be bound so closely against the interme diate portion 9 of the head 8 as to render the pivotal movement of the head 8 dillicult, the screw may be manipulated to swing the head 9 on the trunnions 3 and thus effect a release of the cam 2 from the scraper 14:.

it is to be noted that when the head 8 is tilted slightly to release the hold of the cam 2 on the scraper 14, the oblong trunhions 3 will prevent the head 8 from be coming detached from the trunnions, it being possible to detach the head from the handle only when the scraper 1 1 stands in approximate parallelism with the handle.

If desired, adjusting elements such as screws 25 may be mounted in the cam 2. "V /hen a scraper blade approximating the thickness shown in Fig. 2 is employed the screws 25 are retracted, but when a thinner scraper blade is used, the screws 25 may be advanced slightly thereby to increase the eccentricity of the cam and to make the cam effective as a holding means.

Having thus described the invention, what I claim is 1. A scraper embodying an arched head comprising side arms having journal apertures, the side arms being provided in their edges with reduced slots which open into the journal apertures; and a handle includgrip and a transverse cam, the cam being terminally journaled in the head and 00- operating With the head to form a blade holding means, the handle including an car; a movable element in the ear and forming a stop for the head; and movable means in the cam adjacent its ends for varying the eccentricity of the cam, the said movable means being adjustable independently of the grip portion of the handle.

In testimony that I claim the foregoing as my own, I have hereto ai'hxed my sigma 25 ture in the presence of two Witnesses.
